摘要
提出了一个基于盲签名技术的智能合约模型,设计融合部分盲签名算法的智能合约执行流程,同时引入管理节点的概念,防止任何参与方的共谋及对智能合约的恶意篡改,分析表明该模型具有良好的安全性且有效地提升了智能合约的隐私保护性能。
A smart contract model based on partially blind signature technology is proposed. A smart contract execution procedure based on blind signature algorithm is designed and the concept of minimally trusted managing node is introduced to prevent any involved party from colluding to tamper the contract and attacking the contract process. The analysis shows that the model has the main features of security and can enhance the privacy protection performance of smart contracts effectively.
